Specification of Letters Patent.

Patented Nov. 12, 1918.

Application filed December 11, 1917. Seria1No.206,697.

To all whom it may concern:

Be it known that I, Room ODoNNELL, a citizen of the United States,residing at Milwaukee, in the county of Milwaukee and State oflVisconsin, have invented certain new and useful Improvements in Baling-Presses, of which the followin is a'specification, reference being hadto t 1e accompanyin drawing, forming a part thereof.

This invention relates. to baling presses for scrap metal and similarmaterials and the object of the invention is to improve the constructionof baling presses in the manner to be hereinafter described and claimed.

Referring to the drawings which accompany this specification and form apart hereof, which drawings illustrate an embodiment of this invention,and on which drawings the same reference characters are used todesignate the same parts wherever they may appear in each of the severalviews, Figure 1 is a vertical, longitudinal section of the press, partsbeing broken away and parts being shown in section; Fig. 2 is a planview of the press with the cover drawn back; Fig. 3 is a verticalsection taken on the line 3-3 on Fig. 2,-looking in the directionindicated by the arrows; Fig. 4: is a partial sectional view on anenlarged scale and illustrates details of construction; and Fig. 5 is aview similar to Fig. 3 but illustrating a different construction.

Referring to the drawings, the reference numeral 1 designates a cylinderand 2 a plunger of a ram which is preferably a hydraulic ram. Theplunger 2' is adapted to be moved forward and back in a box 3 which isprovided with a movable cover 4. The cover 4 is held securely to the topof the box 3 in any suitable manner as, for example, by projections 5 onthe cover engaging projections 6 on the box. The cover is preferablyprovided with antifriction devices, such as rollers 7, which can run onthe tops of the sides of the box and on rails 8 and 9.

A cylinder 10 and piston rod 11, which is.

connected to the cover 4, are power mechanism for moving the cover 4forward and back by power. The plunger 2 is preferably enlarged by ahead 12 at its outer end and supported bv antifriction devices 13 and,

when placed horizontally as shown, may be ulled back or retracted by aweight 14. The box 3 has one end open and the other end closed. Adjacentthe'closed end 15 of the box and opposite the cover 4 is an aperture 16through which can pass the enlarged head 17 of the plunger 18 whichworks in the cylinder 19. The plunger 18 and the cylinder 19 form a ramwhich is preferably a hydraulic ram.

The head 12 of the plunger 2 is provided with corrugations or Vs 20 andthe cover 4 is provided with matching corrugations or Vs 21 which extendthe full length of the stroke of the plunger 2 and to the extreme frontend of the cover. The bottom and sides of the box 3 are also providedwith corrugations or Vs 22, 23 and 24, which match the corrugations orVs of the bottom and sides of the head 12 of the plunger 2, but whichextend only the length of the stroke of the plunger 2 and terminate atthe edge of the aperture 16. The corrugated construction of the plunger,the cover and the bottom and sides of the box is to prevent pieces ofmetal from being caught and wedging between the head 12 of the plunger 2and the cover 4 or the bottom or sides of the box 3 when the plunger isbeing moved or when the cover is being moved.

The head 17 of the plunger 18 may also be provided with corrugations orVs in the same manner as the head 12 of the plunger 2 and the front faceof the head 12 of the plunger 2 and the end and sides of the box 3engaged with the head 17 may be provided with matching corrugations orVs extending in the direction of movement of the plunger 18, but, forthe sake of simplicity, these parts are illustrated by the drawings assmooth or plane surfaces.

Face plates 25 and 26 may be applied to the heads 12 and 17 of theplungers 2 and 18' and will be shaped to conform to the surfaces withwhich they engage. The face plates may be provided at their edges withyieldable flaps 27 and 28, which are shown by the drawings as applied toonly one edge of a face plate. Suchyieldable flaps may be hinged to theface plates by hinge pins 29 and normally held against a plunger head byone or more springs 30. The flaps may have their rear edges rounded orbeveled at 31 to provide clearance.

The reference numeral 32 designates a conveyer trough in which anysuitable conve'ying mechanism (not shown) may move the bales to anydesired point.

When yieldable flaps are used at an edge of a face plate, thecorrugations or ls must The operation of the press as f L elion's. Theplunger 12: is lowered until its heed 17. or the face plate 26, lies inthe apertu e 16 thus providing a bottom for the box this point. Theplunger 2 and the cover t are pulied hack and the scrap dump into thebox. The open end of the hey the head 12 of the course closed h he cererl; is then pushed rern'iird compre; nerd. A mil is thus formed '5further ocinpreseed by then nun" plunger 1.6 up.
